2SC3052

Changjing · Bipolar (BJT) · SOT-23

2SC3052 from Changjing, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 BASE input Base terminal of the NPN transistor, with the emitter-base voltage rating VEBO limited to 6 V.
2 EMITTER passive Emitter terminal of the NPN transistor; the emitter-base breakdown voltage V(BR)EBO is specified at 6 V with IC=0.
3 COLLECTOR passive Collector terminal of the NPN transistor, rated for VCBO and VCEO of 50 V, continuous collector current IC of 0.2 A, and collector power dissipation PC of 150 mW.
